ZF 4699.171.023 WHEEL | OEM Genuine Part

Overview

The ZF 4699.171.023 WHEEL is a critical load-bearing component within the planetary gearset of heavy-duty construction machinery transmissions. This OEM genuine part, identified by SKU 4699.171.023, functions as the primary interface between the sun gear and the planetary carrier, ensuring precise torque distribution and rotational stability. Located in the final drive assembly, this wheel absorbs high axial and radial loads during operation, making it essential for maintaining gear alignment and preventing premature wear on adjacent housing components. When paired with a properly sealed 4699101043 HOUSING, the wheel ensures consistent power transfer under extreme load conditions.

Symptoms of Failure

• Erratic gear engagement and slipping – Worn wheel teeth cause intermittent power loss during acceleration, especially under load in ZF WG180 transmissions.
• Metallic grinding noise from the final drive – Surface spalling on the wheel creates a distinct high-pitched whine or grinding sound during low-speed operation.
• Contaminated transmission fluid with metallic particles – Flaking material from the wheel surface appears as silver or bronze debris in the oil filter or drain plug.
• Increased backlash in the planetary gearset – Excessive clearance between the wheel and mating gears leads to delayed response when shifting between forward and reverse.

Technical Specifications

Compatibility

This wheel is engineered for ZF’s WG series powershift transmissions commonly used in wheel loaders, graders, and compactors. Based on its design and dimensions, it is compatible with the following ZF transmission models: WG180, WG200, WG210, and WG250. It also fits select variants of the 4WG200 and 5WG200 series. For proper installation, ensure the mating 4699301106 HOUSING is free of scoring, and verify the 4699301015 HOUSING COVER is torqued to factory specifications. The 4699301085 COVER must also be inspected for cracks during reassembly.
